JOHN G. FINLEY, or DECATUR, ALABAMA.

CLOD-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 721,170, dated February24, 1903. Application filed September 27, 1902. Serial No. 12 5,066. (Nomodel.)

My invention relates to machines for rolling fallow land, and has forits objects to provide a frame having a series of wheels journaledtherein, the said Wheels being provided with rims having a face suitedto the groundvthat is to be treated, which might be fiat or at anydesired angle, and hubs which extend 'outward a fraction of an inchbeyond the plane of the edges of said rim, so that when the wheels arearranged in a series on a shaft the wheels are spaced apart from oneanother to permit them to cut into the soil, and thus add greatly to itsefficiency, as also to permit any particles of earth that may be caughtbetween the wheels to work out again.

The advantages of my invention will more fully appear hereinafter and byreference to the accompanying drawings, in which.

Figure 1 is a side view in elevation of my invention; Fig. 2, a top planView, and Figs. 3, 4, and 5 views in section of difierent types ofwheels that may be used with the machine.

Referring to the drawings, in which similar reference charactersindicate corresponding parts throughout the several views, A representsthe frame of my machine, which, as shown, is made preferably of arectangular shape, and B is a draft-pole secured to said frame directlyand by means of anglebraces C.

D represents boxes secured on each side beam of the frame A, in which isjournaled a shaft E, the journal-boxes D'being of a type that willpermit removalof shaft E for the purpose hereinafter specified. V

F represents crushing-wheels, which are preferably made of thespoke-and-rim type to conduce to lightness in draft; the rim G of whichis beveled at a greater or less angle, as shown' in Figs. 3 and 4, orflat, as shown in Fig. 5, the purpose being to furnish with eachcomplete machine a set of the several forms of Wheels, so that theoperator may select the boxes D.

wheels F are loosely mounted on the shaft E,

so that each rotates independently of the others, aswell as collectivelywith said shaft E, which, as above stated, is 'journaled in Y It willalso be understood that the wheels with the angle-rims may be soarranged that the pitches of the rims are toward each other or V-shaped,as shown in Fig. 1, or so that the pitch is in the same direction or onparallel planes, as best suited-to the work to be performed. The hubs Hof the wheels are made longer than the width of the rim G, so that thewheels when placed on the shaft are spaced apart. This structure allowsthe wheels to sink into the soil and cut through large clods, thus morethoroughly performing the work, as well as permitting any particles ofearth that may be caught up by the wheels to find ready egress.

Irepresents a rod pivotally secured on the rear beam of frame A, havingweighted angular extensions K, and L scraper-blades removably securedthereto for cleaning the rims of wheels F, it being readily understoodthat the scraper-blades L must be shaped to .fit the angle of the rims Gof the wheels when arranged with pitch toward each other or on parallelplanes, as above described, and also wheels of varying pitch, the bladessuited for the difierent rims and arrangements of wheels being suppliedwith the machine and being transferable on rodI by any suitable means.

Having thus described my invention, what I claim is In a clod-crusher,the combination of a suitable frame,a shaftjournaled thereon,crusherwheels journaled on said shaft, each of said wheels having itsrim beveled in a single direction and having hubs longer than the widthof said rim, a rod pivoted on said frame having weighted angularextensions, and interchangeable scraper-blades removably and JOHN G.FINLEY.
